When to Choose Zilliz Cloud vs Redis Vector Store
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Milvus scales to trillions of vectors using hierarchical index structures with tiered storage, serving billion-scale collections that exceed single-machine memory limits via Zilliz Cloud managed deployment.
Add vector search to an existing Redis deployment for product recommendations with sub-millisecond response times
Milvus GPU indexing builds IVFPQ indexes on billion-vector collections 10x faster than CPU-only builds, reducing the time from ingestion to searchable index for large-scale embedding pipelines.
Milvus partitions split a collection by tenant key, improving query isolation and allowing partition-level operations like load/release to balance memory usage across a shared cluster.
Store conversation embeddings in Redis and retrieve semantically similar past interactions for context-aware chatbot responses
Compare transaction embeddings against known fraud patterns in real-time at low latency to flag suspicious activity during checkout
Combine Redis caching and vector search in one database, reducing infrastructure complexity for recommendation APIs

Strengths & Limitations
Evaluative strengths and weaknesses: not feature lists
- +CNCF project: battle-tested for billion-scale workloads
- +GPU acceleration and DiskANN for cost-efficient large-scale search
- +Distributed architecture with independent storage/compute scaling
- +Multi-vector search supports complex AI use cases
- −Operational complexity: requires Kubernetes expertise for self-hosted
- −Overkill for small-scale RAG applications
- +Sub-millisecond vector search latency for applications already using Redis
- +No new database to manage if Redis is already in your stack
- +HNSW index delivers high recall with low query latency at moderate scale
- −There are some points where I feel Redis can be improved.
- −There are a few areas where Redis could improve.
- −Redis could improve its efficiency in handling locally stored data, not just Amazon Cloud or Google Cloud.
- −Redis presents a single point of failure and lacks fault tolerance.
- −The product's main purpose is caching, even though the vendor says we can also use it as a persistent database.
